• VCS-E SRV Records for several regions of the

  I have a region of production with a cluster of 2 highways and a test with one Highway area.

  Since I've implemented the first test area, I SRV records in place for Highway test:

  Here is an example of 1...

  _sip._tcp.example.com. 86400 IN SRV 10 10 5060 testvcsx.example.com

  How do I set up the SRV records for the production cluster using the same domain (example.com) but still be able to separate my production and test records, call the traffic, etc.?

  Hi André,.

  somehow, he must distinguish between prod and test platform.

  I would say to leave the field of prod to be like (referring to your example) example.com and trying to be test.example.com

  The answer DNS SRV is a recordset in the format:

  _ service. _ Protocol... TTL class SRV priority weight Port target

  When the target is a record setting the destination and for a cluster, it may be FULL of the cluster domain name.

  so if you have a cluster as prod and autonomous as a test, you can implement it like this:

  _sip._tcp.example.com. 86400 IN SRV 10 10 5060 vcscluster.example.com

  and you test domain is resolved by:

  _sip._tcp.test.example.com. 86400 IN SRV 10 10 5060 testvcsx.test.example.com

• Question VCSE Bind9 Dns Srv record

  Hi all

  I recently put in place a solution of VCS Express in my area, but I need your help to solve my problem of dns.

  My infrastructure is:

  1 VCSE optional NIC for dmz 2 and natted with the public IP address

  VCSC lan subnet 1

  Everything works fine, covered call, record (Movi) from the outside, call SIP/h.323 IP or dns, interoperability... Everything is ok

  My question are dial endpoint not registered.

  When I call to outsite in:

  [email protected] / * /, working (I create a processing rule to convert the IP to the domain)

  [email protected] / * / work but the search rule failed in agreement with my search rule

  [email protected] / * / Is not no incomig call

  I suspect that there is a misconfiguration of the dns.
  We use servers DNS Bind9 as authoritative for our area

• A & QUESTION SRV RECORD

  I have a real?

  Have a network of VCS X8.2.2 of two cluster control.

  I was running a three server cluster, but due to latency issues took the VCS3, I deleted from the cluster and makes it independent.

  I removed the intellectual property of the counterpart of cluster list also.  That was months ago.

  Problem is this morning when systems checking, I noticed that one of my VTC systems was recorded on the single VCS3 media... Problem is in the system in the H.323 call control settings, I have the SRV cluster name and not the IP address of the VCS3 yet he him?

  I don't want any system recorded in the autonomous VCS3 and want to keep the name of the SRV cluster in the area... ???  I changed the doorman affecting intellectual property SRV record and he also recorded for the VCS3...?

  What could be causing this to happen?  Also, the priority is set to one on all of the SRV records.

  VR

  Chet

  I suppose that you in fact removed the old SRV records and replaced by a new that has not listed of VCS - C3?

  If you want to ensure that no system is able to register with that specific VCS, define a strategy of 'Decline' record for the sub-area of default and all other Subzones, you might have on this VCS.

• VCSE and SRV records

  Hello world

  I have a general question about the SRV records and just need a bit of clarification. I have a client who has registered a domain for their express VCS, (tp.example.com). When I do a dns lookup it brings back the correct public ip address of the vcse. Now, I'll be confuring this system few however I don't know anything about SRV records.

  What I should allow the client to pass the SRV records relevant to their ISP for their external dns host?

  The public domain of customers is also identical to their internal domain. Im guessing the correct SRV records must be added to their server DNS internal too?

  Thanks for your help

  PS Si there is a good guide on adding files, srv etc then ide grateful if you could send me the link. Thanks again

  As we do not know your deployment it's hard to say, as if you have a cluster internally

  you use SRV records to sign up customers to allow failover. But who would most likely be

  some additional DNS entries and not necessarily the same as outside.

  If the systems are registered in their own country, they can work very well with no SRV record for the video domain.

  For external connectivity SRV records are more important.

  If you have a provider maintains the entries external DNS is the question put in place

  the SRV records.

• Motorway E overlap in srv records

  Hello

  In a design of the Express way, using a cluster of Highway MRA for registration and another cluster for B2B call (and jabberGuest).
  We use the domain name "example.com".
  This means that clients jabber and video endpoint use the URI as [email protected] / * / your registration through cluster MRA.
  If outside the appeals of a jabber client or a videoendpoint on the "example.com" domain call must pass through the pole B2B.
  Question:
  The sips 5061 SRV records must be made on the domain 'example.com' but where it should point the MRA cluster or Cluster B2B?

  For ARM, you only need the SRV tip collab.  According to the Expressway Administrator's guide, it is said of SIP SRV record is not necessary for mobile and remove access.  The SIP SRV should point to your cluster B2B Expressway, for incoming calls.

• VCS Cluster - record H.323

  Hi all

  We have a VS Cluster and would like to register 2 MCU´s and a gateway with H.323 on it.

  -Inscription on the first not peer very well - no prob. record of 2. Peer - does not (source unauthenticated received fron)

  VCS Trace... no this crypto token / / invalid cryptographic tokens.

  Its allways happened on 2. peer.

  Restart the MCU, restart Cluster, see time servers, disabling / enabling H.323 in VCS and MCU - all done, always the same failure.

  VCS Cluster / MCU / ISDN are all in the same subnet, but in another location. RTD between the location is less than 10 ms.

  BTW: SIP with tls runs without any risks.

  Does anyone have an idea?

  Thank you much for your helping hands

  /Dirk

  In general this should not happen.

  You said you checked the time servers, but have you also checked the actual time on the

  VCS and the endpoint? (for example the login as root and check with the date).

  Try to use the same NTP server on all VCS and endpoints.

  Is the group itself ok (see configuration / clustering)?

  Something not ok with the zone configurations?

  You have any local specific or server based CPLs on VCS?

  No matter what firewall/nat/alg between VCS and the endpoint?

  Do you have a xconfig on two VCS and compare the config of the differences?

  Your sure it's the right vcs you hit?

  Do you still review log files and compare what's happening the first relative to each other?

  A tcpdump and check on the VCS of debugging can be interesting as well.

• Question record DNS SRV + VCS Expressway

  Hi all

  I have a South, VCS in the DMZ, and I am facing a problem with the SRV DNS records.

  VCS Expressway Hostname:-VCSe

  Domain: example.com

  FULL VCSE domain name: VCSe.example.com

  and I have an a record set up for the same FQDN in DNS Public Server.

  I have a sip domain configured as 'cisco.com' in my VCS Expressway.

  What is the SRV records, I need to create in the Public DNS server.

  Kind regards

  Nikhil Jayan

  Nikhil,

  It seems that you have not checked the link I sent you earlier... A very explicit documents. in any case that we talked about earlier is we were talking about signs send calls to the highway as well as parts of the record.

  In your deployment, you have a different domain for DNS and SIP domain. Also as you say you meet Highway cluster and you want to record to both endpoints and then I suggest you to check the document for the creation of cluster on cisco webesite.

  Now, if you have a cluster for Highway then you must create several srv records that would be pointing to each domain name FULL of the approved cluster with equal weight. In normal use scneario of domain common to different services are recommended.

  Srv records would have seen something like that.

  _sips._tcp.company.com. 86400 IN SRV 1 1 5061 vcse1.company.com.

  _sips._tcp.company.com. 86400 IN SRV 1 1 5061 vcse2.company.com.

  _sip._tcp.company.com. 86400 IN SRV 1 1 5060 vcse1.company.com.

  _sip._tcp.company.com. 86400 IN SRV 1 1 5060 vcse2.company.com.

  _h323ls._udp.company.com. 86400 IN SRV 1 1 1719 vcse1.company.com.

  _h323ls._udp.company.com. 86400 IN SRV 1 1 1719 vcse2.company.com.

  _h323cs._tcp.company.com. 86400 IN SRV 1 1 1720 vcse1.company.com.

  _h323cs._tcp.company.com. 86400 IN SRV 1 1 1720 vcse2.company.com.

  _h323rs._udp.company.com. 86400 IN SRV 1 1 1719 vcse1.company.com.

  _h323rs._udp.company.com. 86400 IN SRV 1 1 1719 vcse2.company.com.

  However, your case is different. In your deplyoment what you have to do is any request for the domain "cisco.com" should be resolved in FQDN of the VCS-Highway peers with equal weight.

  for example

  _tcp.gmail.com. IN SRV 20 0 5222     talk2.l.google.com.

  Therefore, any request to gmail.com would resolve to the talk2.1.google.com server.

  same way you have to make it work.

  Thank you

• DX70 record on ARM.

  Hi all

  Please suggest me on DX70 inscription on ARM.

  I've updated dx 70 with the latest firmware

  sipdx70.10 - 2-4-99

  I am geeting under option in DX70 after rebooting with the new Firmware

  The highway connection information

  • Name of the service:
  • User name:
  • Password:

  Please suggest me what I have to add in these areas because I tried under options

  1)

  service name: cisco.com

  username: sushants

  There [email protected]/ * /.

  (2) name of the service: collab1.cisco.com (expressswaye FULL domain name)

  username: sushants

  There [email protected]/ * /.

  Both his can't e expressway.

  I checked the event logs.

  These are the same references that you use for the Jabber MRA connection. Do you have customer work Jabber which has already been put into operation successfully and may be able to connect?  Connect to Jabber via ARM to ensure and verify the MRA functions operate. Use the same credentials to sign in on your endpoint DX70 via Highway-E.

  Name of the service:

  User name:

  Password:

  What version of the firmware of your CV (Expressway-E)? You must run X8.5 or later to support endpoints DX using VCS via ARM.

  Check also if the public (external) DNS configured with _collab - edge._tls.  SRV records so that endpoints can discover highways VCS for ARM.

  In your case, for example:

  FQDN of the highway-E = collab1.cisco.com

  Domain = cisco.com

  Check from a Windows computer on the Internet, open a command line and do nslookup:

  To verify the a record, type:

  Nslookup collab1.cisco.com

  The response must include the corresponding Expressway-E
  public IP address

  To verify the SRV record, type:

  Nslookup-type = srv _collab_edge.tls.cisco.com

  The response must include the domain highway-E FULL name

• Endpoints VCS component the outside world

  Hi guys,.

  I can't find information about endpoints SIP calls from outside the organization.

  for example, I found a person, there a sip address - [email protected] / * / through which I can reach. I want to call him to registered VCS infrastructure endpoint. something about it is in this document (page 28), but there is no accurate confirmation on my suggestion.

  It is possible at all? and what I need to deploy that?

  Thank you!

  Create the rule of research according to the documentation - it's all you need to do. To confirm that it works correctly, you can test it with the closure of Cisco service which will loop your own video to you; call [email protected] / * /

  To dial [email protected] / * / you do not have to do anything at all, however, the people/organization you call must have the SRV records appropriate in place - even for you, if you want people to call you using the [email protected] / * /, then you must have in place appropriate SRV records.

• Cisco VCS and LDAP for authentication of users

  I have a question about setting up LDAP for authentication of the user on the VCS. I want to have redundancy in my LDAP link. I believe that this is possible by setting a FULL domain name to the address of the LDAP server, then selecting a type of SRV resolution. What I'm not clear on is what the value for the server address would be if I used actually as SRV type of resolution. I should also add that I am looking to use TLS

  To clarify, if my AD domain name is myad.netcraftsmen.net. I have set the field as server address:

  myad.netcraftsmen.NET: assuming that VCS properly interrogate the DNS for the _service._proto correct parameters?

  or would I need to create an SRV record to that effect and set the field server address with the address (including the fields of _service._proto)

  or I need to specify one of the SRV records formats used by MS AD areas (there are several).

  If the latter, then what SRV record for TLS. I don't see records with port 389 (non-secure).

  My intuition tells me that this is probably the first option, but I could be far away.

  Anyway, thanks in advance for any input.

  Kind regards

  Bill

  Hi William,.

  I just checked it on a X6.1 VCS, and it seems that VCS searches SRV _ldap._tcp.domain (where 'domain' has been entered as the server address), both when the encryption is set to 'None' and 'TLS '.

  Hope this helps,
